He was there too and was read the charges. I think the media is focusing on her because she is the more famous. I vaguely remembered his name when they said he was a clothing designer. Then I remembered his name is on some labels of Target clothing I own. But, he hasn't designed for Target in a few years. Otherwise, his name would now be dragged through the mud too.
As for William H. Macy, he was implicated in either phone calls or emails Felicity wrote. But, he hadn't written any emails of his own, or made any phone calls that were recorded and catching him committing a crime. According to my unprofessional, "TV legal dramas" experience

even though Felicity said he knew about what was going on, it's considered Hearsay (talking about someone in the third person,) and not admissible in court. So he hasn't been charged with any crime. Plus, I think if they were going to try to charge him, if they could, Felicity would throw herself under the bus for him and say she lied. That he really didn't know any of what she was doing. She only said he knew. Their marriage is tight. It's bad enough one of them would be going to prison. And one career ruined.
I can't find any report that says he went to court with Felicity. She came alone with her lawyers. It could be that his PR people or her lawyers are trying to distance him from this. He still is a star of the show
Shameless, which is coming back for a 9th season.
